10839986 · 2020-11-17 · ·

An electrical conductor comprises three or more solid segments of identical shape. In cross-section, each segment comprises two sides, which are configured for flush bearing against correspondingly opposing lateral surfaces on another segment. The cross-sectional surface through all the constituent segments of the electrical conductor is describable by a closed curve having a stepless characteristic. All the constituent segments of the electrical conductor are stranded in combination.
